Critical Success Points

• • Sift dry ingredients to avoid lumps.
• • Whip eggs and sugar over a double boiler for a stable foam.
• • Fold dry ingredients gently to preserve air.
• • Bake just until set (≈12 min) to keep the sponge flexible.
• • Roll the cake while still warm.
• • Spread ganache and roll promptly; reserve ganache for topping.

Safety Warnings

• • Hot water and steam from the double boiler can cause burns – handle with care.
• • The oven and hot baking tray are extremely hot; use oven mitts.
• • Ganache is hot; stir carefully to avoid splatters.
• • Raw eggs carry a risk of salmonella; ensure the egg mixture is cooked by the heat of the double boiler and the baking step.
